A Commercial Energy Performance Certificate (EPC) measures the energy efficiency of non-domestic properties. Whether you own an office, shop, warehouse, or restaurant, a Commercial EPC is a legal requirement in the UK when selling, leasing, or constructing a commercial building.

Understanding what assessors inspect during a Commercial EPC can help property owners prepare and ensure a smooth assessment process.

What is a Commercial EPC?

A Commercial EPC provides an energy efficiency rating from A (most efficient) to G (least efficient) for business properties. It also includes:

  • Carbon dioxide (CO₂) emissions

  • Estimated energy usage

  • Recommendations for improving energy performance

  • Compliance with legal requirements

Commercial EPCs are part of the Minimum Energy Efficiency Standards (MEES), which require most leased or rented properties to achieve at least an E rating.

What Happens During a Commercial EPC Inspection?

During an inspection, an accredited assessor evaluates key energy-related aspects of the building. This ensures the energy rating accurately reflects the property’s efficiency.

Key areas assessed include:

1. Heating and Cooling Systems

  • Type and age of boilers, chillers, or heat pumps

  • Efficiency of central heating or air conditioning systems

  • Controls such as thermostats, timers, and zoning systems

2. Lighting Efficiency

  • Type of lighting (LED, fluorescent, incandescent)

  • Presence of motion sensors or energy-saving lighting controls

  • Energy usage patterns for common areas and workspaces

3. Ventilation and Airflow

  • Mechanical ventilation systems

  • Natural ventilation and windows

  • Energy efficiency of air handling units

4. Insulation Levels

  • Roof and wall insulation

  • Floor insulation (where accessible)

  • Windows and glazing type

5. Hot Water Systems

  • Boilers and water heaters

  • Efficiency of hot water distribution systems

  • Storage tanks and insulation

6. Property Size and Construction

  • Total floor area and building layout

  • Construction materials (brick, concrete, steel)

  • Age of the building and design features affecting energy usage

How Long Does a Commercial EPC Take?

  • Small commercial units: Around 45–60 minutes

  • Medium to large offices or retail spaces: 1–2 hours

  • Large warehouses or complex buildings: Several hours

The time depends on building complexity, size, and energy systems.

What Happens After the Inspection?

Once the assessor collects all necessary information:

  1. Data is entered into government-approved EPC software

  2. The energy rating is calculated (A–G)

  3. The certificate is uploaded to the official EPC register

  4. Property owners receive the commercial EPC, usually within 24 hours

Benefits of a Commercial EPC

  • Ensures compliance with UK energy efficiency regulations

  • Helps identify areas to reduce energy bills

  • Provides recommendations to improve building efficiency

  • Enhances the marketability of commercial properties

Commercial EPC Costs

  • Starting from £145 for small units

  • Larger or complex buildings may cost more depending on size and systems
